How the get the modified URI of a Request object after modifying the query through the "query" object?

In a request listener I get a Request where I need to check the presence of certain query parameter, and if it exists, redirect to a slightly changed URL:

So I check Request::query and modify accordingly.

if ($request->query->has('foo')) {
    $request->query->set('foo', 'bar');
}

if ($request->query->has('baz')) {
    $request->query->remove('baz');
}

But after this I call:

$request->getUri()
$request->getRequestUri()

… and the returned URL still has the original values for foo and baz in the query string.

Can I get the modified URL directly from the request object?

Thanks, regards.

>Solution :

If you have a look inside Symfony code you might understand better what you’re doing.

Here is the method set or the query:

public function set(string $key, $value)
{
    ... some verification

    $this->parameters[$key] = $value;
}

It does change an array of parameters.

The methods getUri or getRequestUri on the other hand are method from the request and not the $request->query and they do not care about $request->query->parameters

I don’t exactly know what you’re trying to do, but if you’re trying to redirect to a given route whith given parameters when you have given parameters you could try something like this in your controller action:

return new
RedirectResponse($this->router->generate(‘your_route’, $request->query->all());

Or building your own array of parameters rather than using $request->query->parameters and then redirect to your route.
